Hello,
Yes, you are correct. You can do this with CSS. You will need to make a local copy of the tablmaster.css file in your theme folder. If there is no ‘css’ folder inside your theme folder then you will need to create one. Then, copy wp-content/plugins/tablemaster/css/tablemaster.css to wp-content/themes/<your theme>/css/tablemaster.css.
Then, edit the tablemaster.css file to set the background color for the cells in alternate columns. It appears you are not currently using tablemaster for the tables on the site at the link you provided. So, if you want to use the default table styling you would add this to the tablemaster.css file:
[ Moderator note: code fixed. Please wrap code in the backtick character or use the code button. ]
/* Define the background color for all the ODD table columns */
#table tr td:nth-child(odd){
background: #b8d1f3;
}
/* Define the background color for all the EVEN table columns */
#table tr td:nth-child(even){
background: #dae5f4;
}
If you wanted to use one of the styles provided with tablemaster, you could do this instead: For example if you were using the ‘red-header-only’ class
/* Define the background color for all the ODD table columns */
.red-header-only tr td:nth-child(odd){
background: #b8d1f3;
}
/* Define the background color for all the EVEN table columns */
.red-header-only tr td:nth-child(even){
background: #dae5f4;
}
Where you place these statements in your local tablemaster.css file in relation to the other CSS statements for the class is important. Be sure to place these statements at the end of the all the statements for the class so that they are applied after all of the other statements are applied.
Good luck,
Valerie
